I don't have knock retard option on my AEM EMS enabled at the moment. It was pulling a ton of timing out. I'm seeing around 1.2v and spiking to 3.0 volts or so on a typical wot pass at 8psi 15* timing on E85. 8.6:1 compression ratio. I believe I'm super conservative here. Pulled the plugs and I see no signs of detonation.

readings seem almost identical between the two knock sensors. Is 3v normal for round 4400rpm?

My build is nothing special stock 5.3, 6.0 heads, zr1 cam and valve springs. I am running a glide thats a bit noisy and solid motor mounts.

Just wondering if these voltages seem "normal"

Thanks!

 

A noisy trans can certainly set off a knock sensor

MBT on the LS6 heads is 22 degrees, with only 8 lbs on e85 I don't see why you cant run MBT

 

I'm sure I can run alot more timing. Just taking it slow, only have 1 full pass on it and zero dyno time.

I checked all the plugs and they looked great. i'll bump it up a degree at a time and watch the plugs.

Thanks!
